Adventures in Qikking

Since the beginning of Feburary 2008 I have been in the unique position to both own an imported Nokia N82 Symbian-based smartphone as well as have access to the beta trial for a new application and website that utilizes the platforms hardware and software potential and is called Qik. Based in San Mateo, CA the start-up currently creates software for Symbian powered mobile smartphones from Nokia, with plans to expand their client to other capable smartphone platforms like Windows Mobile in the future. Qik enables these advanced mobile smartphones to stream video using their built-in camera to the Internet, live, while receiving feedback in real-time from viewers on the Qik website. Qik also enables users to easily share and upload their videos to other video-centric websites like YouTube, Seesmic, and Mogulus while offering integration and notification to Pownce, Twitter, and Blogger.

Think about that for a moment there. Live video to the web, with viewer feedback. Real-time.

This is the kind of use for advanced technology that allows one to talk about enabling citizen journalism on a massive scale without getting laughed out of a room full of journalism majors, or worse, broadcasters. However, one point that established media types will bring up is the concept of GIGO. Garbage in, garbage out. People used to watching news on major broadcast networks have a very high expectation of quality when it comes the the finished video product. Conversely, people who go to video websites like YouTube have a much lower expectation of quality because they don’t see it as competing with television or other traditional broadcast networks.

What does this mean for something like Qik however? It means that if people are going to use this application for something more serious then the more trendy lifecasting applications there has to be a concerned effort to work at improving the quality of the video output to Qik both in content and in raw video quality also. Improving the content of Qik videos is something that is outside of the scope of this article, but improving the raw video quality from Qik is not.

The biggest problem with getting good video out of these phones comes from the fact that they are, in essence, phones. There are camcorders that take better video, cameras which shoot better quality pictures, in essence these phones are technological compromises albeit getting less compromised with each revision. One of the biggest complaints about video quality however arises from Jerky-Cam(tm) a.k.a hand-holding the phone and not holding it steady enough. This has a two-fold effect on the video due to compression being done on the video. First, the video becomes more and more garbled as the codec struggles to keep the output video within the boundaries of the bandwidth limits its settings. Secondly, this additional movement causes the codec to spend more bits encoding movement leaving less bits available for detail in the scene.

The easiest way to combat shaky-cam is to mount the camera onto a tripod, yet this introduces some issues that are unique to the mobile video world I suspect. Chief among these is portability, after all we are talking about taking a small phone and now having to lug around a tripod that is many times the size and weight of the phone itself. More important however is the fact that the phone manufactures havent seen fit to add a standard 1/4″ screw thread mount point to their cameraphones, making use on photographic or video tripods more problematic then it should be.

After looking around the market for solutions to this problem I had a brainstorm and came up with the following solution that I think is a good first step towards getting better video out of Qik and other video applications on the cameraphone in the future. Manfrotto is a well known and respected manufacturer of tripods, monopods, and other gear for photo and video professionals. As it turns out they make a self-standing monopod, the 682B, that lets you have a free-standing monopod. While this is not as stable a platform as a traditional tripod would be it is significantly lighter, smaller, and more portable then others. Using this as a platform for a Nokia N82 for use in Qik is a good compromise between size, weight, and stiffness. However, even using the monopod we still need a way to mount the cameraphone on. This is where the Nokia DT-22 universal tabletop tripod comes in. It comes with a screw-tight clamp that fits most all N series phones and easily detaches from the tabletop tripod and will screw onto a standard 1/4″ camera screw. If you wish to point the camera at various angles you will want to invest in an inexpensive ball mount for the monopod like the Manfrotto 484RC2 mini-ball head with quick-release plate mount.

However, we still have some other issues to address that are more difficult to handle with a mobile phone device. These devices are not equipped with the kinds of designs or battery life that enable them to take video for long periods of time, say and hour or more. Most of these phones would be bricks within the inside of an hour of doing live streaming video to the Internet. Because of this we also need a portable power supply to help augment our phones internal battery. This is where the PPC Techs Lil’Sync USB battery power supply comes in. It’s a 4400mah rated Li-Ion battery and it charges via mini-USB and can charge one device via a regular USB port. Combine this with a Nokia CA-100 USB to DC charging cable for your N series Nokia phone and you now have a way to keep the battery lasting longer for video recording.

Now once you have assembled all these parts you may still have one important hurdle left to jump over if you live in the United States like I do, bandwidth. Unless you are using a Nokia N95-3 or N95-4 model designated for North American usage you will have imported a European GSM phone that has support for 3G networks only on European GSM frequencies and at best will only have access to an EDGE class network for streaming your video over. This means that any attempt to stream video, even if on lower quality settings and a 320×240 resolution in Qik will result in instant building delay between what users on Qik.com see verses what you are seeing in real-time with your phone. It also means getting user feedback will be greatly delayed or nonexistent as well. Short of having an N95 with support for North American 3G networks you will have to rely on WiFi networks for streaming. This works in fixed known locations, but not on the road in random places. For these situations there is a final part to this solution made by a company called Cradlepoint.

Cradlepoint makes EVDO to WiFi bridge routers, specifically the PHS300 or Personal Hotspot. The PHS300 has a built-in Li-Ion battery for 2-3 hours of use without having to be plugged into an outlet. Using an EVDO USB adapter or a EVDO ExpressCard/34 combined with an ExpressCard/34 to USB adapter along with a subscription to a subsequent EVDO unlimited data plan you can provide a WiFi signal to your Nokia with sufficent upstream bandwidth to support full real-time video streaming.

At this stage I have assembled all of the parts mentioned in here except for the Cradlepoint PHS300 which is my next step. I may have to machine a custom mounting plate to hold the PHS300 and the Lil’Sync onto the camera ball-head mount. I will report back once I have acquired the unit and looked into integrating it into the monopod.

Ultimately however, there are still some issues with the phone as a streaming video platform. Namely, when someone calls you! When using Qik, if you get an incoming phone call your video will stop streaming and you wont be able to restart your video stream until after you get off of the phone, unless you are using WiFi for your streaming connection from what I have seen. The Qik client itself is also undergoing frequent changes and the company and its main coders are rather open to suggestions and enhancements to the program which is great.

FEAR IT!

All of the information can be found on the Evite which is here:

Evite for Dan’s 32nd Birthday Party!

The important thing to remember is that it is THIS WEEK on SATURDAY. I have email addresses for a lot of you people, but not all of you so I have posted this on MySpace where a bunch of you are as well as on my main blog, Vox, LiveJournal, and Twitter.

Hope to see you all there!

Even Security People need Single-Signon

SF City View from 4th Floor MetreonI’m in San Francisco, CA at the 2008 RSA security conference this week and have been getting my bearings around here. This is the first time I’ve ever been to Moscone Center or the Metreon and so far its all pretty snazzy. Beautiful view of the city skyline from the 4th floor of the Metreon can be found on my Flickr account.

In any event, when you pickup your registration info and show badge you’re handed three things. A show planner, the addendums to the show program, and how to connect to the RSA WiFi network. The howto document for connecting to the wifi is larger then the show program addendum! So while in the press room I attempted to get online with RSA wifi network and discovered that I might as well have been trying to negotiate with the Packet Nazi (motto, “No packets for you!”). So why is this so damned hard? Lets outline the problems here:

  1. Your RSA website name is different from your RSA WiFi name
  2. Your RSA website password is NOT your RSA WiFi password
  3. You must be running an OS that speaks WPA and PEAP. Support WEP only? Tough titties for you.
  4. To get your RSA wifi password, you have to login with a RSA website password not given to you. So you must request it be sent to your email.
  5. Your RSA website login is NOT your email address (seriously, wtf were you thinking guys?

So basically, you have to login to the RSA website with something other then your email address, with a password that is auto-generated for you. Except you dont remember the username you specified, so you have to get THAT emailed to you as well. Then, once you login to the RSA website you can get your WiFi password.

Armed with that password, you then use PEAP and 802.1x to login to the WiFi, EXCEPT your username here is now your email address you used to register your RSA badge with! Basically, I watched a few people in the press room struggle with this, myself included. And in one case, a person had a laptop that only supported WEP and they had to revert to a wired connection. Incidentally, the WiFi instructions document covered only Windows systems and only briefly mentions OS X in it anywhere and doesn’t give instructions for OS X. Where is my FAILboat?

Did I forget to mention that most of these steps you cant do unless you are connected to a network of some kind? Catch-22 galore, yay!

Moral of this story? RSA needs single-signon badly! I mean, why on earth do I need a separate username and password for the RSA website different from my RSA wifi credentials?

Wordpress updated, etc

I finally went ahead and upgraded to Wordpress 2.3.1. I ended up having to uninstall the Bad Behavior plugin because, well, it was behaving badly. Namely when I tried to login to the admin page of my blog from home it thought my home IP address was a known bad IP address which sounds pretty wrong to me. So I went ahead and logged into my server via SSH and tried to login to the admin page using Lynx on the console and Bad Behavior then had a conniption fit about being connected to from localhost which in my book was the last straw. You should *ALWAYS* allow localhost to connect to you dammit, you damn dumb POS overblown PHP script. A quick rm of the Bad Behavior directory got things back to normal thank god.

While I was at it I also updated all of my plugins and tinkered around abit with the backend scripts for the Redoable WP theme I am using in an attempt to get some annoying MySQL errors to stop when I am in the administrative interface with some luck. Apparently the  author of the theme is swamped with real work and uni studies so I can understand their predicament. In the meantime I might go check out the K2 theme people and see where they are these days. Last I looked it was at a point where you had to sync with nightly SVN updates which I thought was rather ridiculous a thing to have to do for a bloody WP theme to work reliably.

More updates to come.

It’s as if millions of EMO souls cried out in agony….

Wait, isn’t that redundant?

Apparently something pretty massive went down at the 365 Main colocation facility in San Francisco at around 1:30pm-ish. More importantly however, this looks like there was a power outage in a large portion of the SOMA district of San Francisco that affected somewhere between 30,000-50,000 people. From what some friends of mine told me there was a total of 6 different blackouts over the course of the last few hours. No word yet on what exactly caused any of this still. Blame chocolate covered manhole covers or the like.

LiveJournal is down! Netflix, down. Craigslist, down. Yelp, down. Technorati, down. Vox, down. TypePad, down.

Yet this is supposedly a AAA-class facility with plenty of online generator backup. Yet all of these major internet websites are down. Why? What the hell happened up there? Did a major transformer in the facility blow or something? Did dickless turn off the containment field or something?

What is even more HILARIOUS is this press release claiming 2-year long continuous uptime just 90 MINUTES before the colossal clusterfuck began. Just to add to the hilariousness of the situation the Onion News Network did a spoof news piece on something similar to this happening that you should all view!

This is why I host my blog and photos on my own server that I have control over and just push updates out to these services. Sometimes even the big guys fuck up their contingency plans.

Testing posting from within Word 2007

So this post is being written inside of Word 2007 using its ability to talk to WordPress in an attempt to see how this works out. Overall I have to say that so far it seems not all that bad. If I had to fault it for anything it would be a lack of SFTP support.

Of course it remains to be seen how one would go about using extensions to the WordPress TinyMCE web editor within Word 2007 itself. Perhaps via way of custom Word macros perhaps? I’m not sure yet.

Changes and other things

So, in case anyone hasn’t looked at the blog recently you will see that I’ve changed the look of things. I’m also trying out MarsEdit to write the post, so we will see if this successfully gets cross-posted to my LJ and Vox accounts. I also got my Google Adsense ads working again on the main site, well sort of. I seem to be having some issues with CG-Inbetween and the Redoable theme, or it could be to do with Wordpress 2.1 perhaps. I’ll have to check more indepth after finals are over.
